Step 1) Secure Name & Obtain Application Form

Before filing a DBA in New Hampshire, double check to see if the name you decided to use as an assumed name is available. You're prohibited from using names that closely resemble a registered business’ name, a political party of New Hampshire or a government authority.

Step 2) Complete The Trade Name Application

The next step is filling out the form online (or you can print it out, in which case you'll need to write legibly), then be sure to get an official copy for your records. The following information is required when filing a ‘doing business as’ in New Hampshire form:

The exact trade name you want to register;

Complete business address;

Nature of business operations;

Date the business was formed;

Name, complete address and signature of applicant.

Once the form is filled out, double and triple-check that all information is correct, then have the registration form notarized.

Step 3) Send In The Completed Application Form

The last final step is to send in the completed form to the Secretary of State’s office for the approval of your New Hampshire DBA application.

A filing fee of $50.00 should be enclosed together with the application form. The address where you can mail your form is found on the actual form as well. After that, await confirmation and you're all set.
